You would hope for brands to be able to talk to the specifics and it might not be in all their advertising front and center. But you know, somewhere on their website, if they go into more specifics about, how they calculate the carbon footprint or like how, what certifications are using for their fiber, that's probably a good indication. 
 That they've thought about it and you sort of want to hear them talk about it across the supply chain from the fiber. So the manufacturing to the transportation and if you hear it across the whole supply chain, then it's probably a pretty good indication that they're being thoughtful about it.
